SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 748,920, dated January 5, 1904.

Application filed April 20, 1903. Serial No. 153,435. (No model.)

To all whom it may concern:

Be it known that we, CAMILLE BRUN and GUSTAVE BRUN, manufacturers, citizens of the French Republic, residing at Lyons, Rhone, France, have jointly invented certain new and useful Improvements in Shuttles, of which the following is a specification.

Our invention aims to provide an improved shuttle for looms adapted for the same uses as the shuttle in our Patent No. 648,547, dated May 1, 1900, and adapted especially for use in the improved loom described in the patent of Brun, Brun, and Bicking, No. 714,665, granted December 2, 1902. The device may of course find use in any other loom which contains mechanism adapted for operation from the shuttle when the thread is exhausted.

Our invention provides various improve ments particularly pointed out in the claims hereinafter set forth.

Referring now'to the accompanying drawings, illustrating a shuttle equipped with an improvement embodying our invention, Figure 1 is a plan of the same. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section through the spindle. Fig. 4 is a view of a portion of Fig. 1, showing the spindle and quill in an upright position and in cross-section near their base. Fig. 5 is a side elevation of a portion of the shuttle, showing the end of the pin.

Our improvement is here'illustrated as applied to a shuttle having a pivoted spindle, so that the spindle may be turned up to insort a quill thereon. A member adapted to be moved to and from a position in which it is operative to stop the loom or to supply new weft thereto or to control mechanism for doing these or similar things is carried by the shuttle. An arm is provided on this member, which arm preferably extends longitudinally within the shuttle andis adapted-t0 be held in a slot in the quill during the ordinary running of the'loom, theweft on the quill surrounding this arm and holding it in place. When the weft is nearly exhausted,

the arm and with it the mechanism-controlling member are released and are moved by a spring to a position in which said member becomes operative.

The shuttle A is provided with a spindle B, normally lying in a horizontal position,

(shown in Figs. 1, 2, and 3,) but adapted to be turned to a vertical'position turning about a shaft 0, and is provided with a squared lower end D, acting in conjunction with the leaf-spring E to hold the spindle in the horizontal or vertical position firmly. The thread is wound on a quill F, which may be of the shape shown or of any other suitable design and which is provided with a slot or groove G, which serves the double purpose of engaging the rib H on the spindle to prevent rotation of the quill and also of receiving an armon a pin hereinafter referred to.

J is a pin extending across the lower portion of the chamber in the shuttle and engaging a shoulder K on the quill to prevent longitudinal movement of the latter when the machine is in operation. Of course when the spindle is turned up the quill is no longer held down by the pin J or any other means, but can be removed endwise and a new one substituted in its place.

For operating certain mechanism in the loom, such as stop-motion mechanism or shuttle-changing mechanism, a pin is provided, which is normally within the shuttle, but which projects outward therefrom automatically upon or just previous to the exhaustion of the thread. Any member adapted to project outward and inward at the proper time is suitable for the purpose. We have shown for this purpose a pin L, which is carried in the hollow shaft 0, on which the spindle turns, said pin being normally pressed toward its outward position by means of a spring M reacting against a transverse pin or other stop in the opposite end of the hollow shaft. The pin is provided within the shuttle with an arm N, projecting through the side of the'hollow shaft C, as illustrated, and held always parallel with the spindle by means of a pair of pins 0 engaging opposite sides of it. A cam comprising a wire P, with its ends fastened in the body of the shuttle, as illustrated in Fig. 1, serves to swing the arm N inward as it is turned upward with the spindle to the position of Fig. 4:, which movement draws the pin L in against the opposition of the spring M. In this position of the parts a quill full of thread is introduced onto the spindle, the arm N entering the slot G and being therefore surrounded by the thread on the lower portion of the quill. Slotted and grooved spindles are known, and the arm N might be moved into such a slot or groove, so as to be in register with the slot in the quill without actually lying in the quill-slot. This is especially the case where slitted paper quills are used, of which the slit may overlie the arm N and be held closed or partly closed by the thread. The spindle and quill are then turned downward, in which position the cam P no longer holds the pin inward. The latter, however, is held by the thread which surrounds the lower end of the quill, and the pin remains withdrawn. The shuttle therefore operates in the usual way. When the thread on the quill is substantially or nearly exhausted, the pressure of the spring M forces the pin L outward, the arm being no longer held by the thread, and this pin engages a desired operating member of the mechanism, as previously stated. The pin L is provided with a flat portion L, (shown best in Fig. 5,) which prevents its rotation by the operating member of the mechanism with which it engages, and thus eliminates any tendency to movement of the spindle which might arise by reason of a frictional force on the periphery of the pin and a consequent rotative tendency.

It is not essential to the broad invention that the pin shall be of the style and be mounted in the manner illustrated. Any member suitably mounted to move to and from a position in which it controls mechanism for supplying new weft or stopping the loom or the like on the exhaustion of the thread is included in our invention. Nor are the various specific elements described all necessary to our invention, except in so far as specified in the following claims.

Though we have described with great particularity of detail a specific mechanism embodying our invention, yet it will be understood that the invention is not limited to'the specificembodiment disclosed. Variousmodificationsthereof are possible to those skilled in the art without departure from the invention.

What we claim is 1. In a shuttle in combination a spindle adapted to be turned up to conveniently place the quill thereon, a quill having a slot, a reciprocable mechanismcontrolling member extending transversely of the shuttle, an arm on said member extending longitudinally within the shuttle and adapted to move bodily transversely thereof with said member, means for holding said arm inward when said spindle is in its turned-up position to permit a full quill to be placed on said spindle with said arm in register with its slot and surrounded by the thread, whereby when said spindle and quill are turned down said member is held in its inoperative position by the thread, and means for moving said member to its inoperative position when the thread is exhausted.

2. In a shuttle in combination a spindle adapted to be turned up to conveniently place the quill thereon, a quill having a slot, a mechanism-controlling member mounted separately from the spindle, an arm on said member within the shuttle, means for holding said arm inward when said spindle is in its turned-up position to permit a full quill to be placed on said spindle with said arm in register with the slot of the quill and surrounded by the thread, whereby when said spindle and quill are turned down said member is held in its inoperative position by the thread, and means for moving said member to its operative position when the thread is exhausted.

3. In a shuttle in combination a spindle adapted to be turned up to conveniently place the quill thereon, a quill having a slot, a mechanism-controlling member mounted separately from the spindle, an arm on said member extending longitudinally within the shuttle, means connected with said spindle engaging said arm to turn the same upward when the spindle is turned upward, a cam arranged to force said arm inward when it is turned upward so as to permit a full quill to be placed on said spindle with said arm in register with the slot of the quill and surrounded by the thread, and a spring normally pressing against said member whereby when said spindle is lowered said member is held in its inoperative position and when the thread is withdrawn from said quill said spring moves said member to its operative position.

4. In a shuttle in combination a pivoted spindle, a hollow shaft therefor, and a mechanism-controlling pin reciprocable therein, and means for holding said pin in its inoperative position until the thread is nearly exhausted and then moving it to its operative position.

5. In a shuttle in combination a pivoted spindle, a hollow shaft therefor, and a mechanism-controlling pin in said hollow shaft and reciprocable therein, a spring tending normally when the shuttle is in operation to project said pin to its operative position, and means for'holding said pin in its inoperative position against the pressure of said spring until the thread is nearly exhausted. V

6. In a shuttle in combination a spindle adapted to be turned up, a mechanism-controlling member mounted in the shuttle separately from said spindle and adapted to be moved to its operative position when the thread is exhaused, and means for moving said member to its inoperative position as said spindle is turned up.

7. In a shuttle in combination a pivoted spindle, a mechanism controlling member mounted separately from said spindle and ad- IIO jacent to the pivotal axis thereof, an arm on said member, and means for turning said arm up as said spindle is turned up.

8. In a shuttle in combination a pivoted spindle, a mechanism-controlling member mounted adjacent to the pivotal axis thereof, an arm on said member, and a pin projecting laterally fromvsaid spindle and engaging said arm on its under side.

9. In a shuttle in combination a pivoted spindle, a mechanism-controlling member mounted adjacent to the pivotal axis thereof, an arm on said member, and a pair of pins 0 projecting laterally from said spindle and engaging said arm on opposite sides.

10. In a shuttle in combination a pivoted spindle, a mechanism-controlling member, an arm on said member, means for turning said arm up as said spindle is turned up, and a cam comprising a wire P with its ends fastoned in the body of the shuttle and its intermediate portion projecting into the path of the arm for moving said'arm inward as it is turned up.

11. In a shuttle in combination a reciprocable mechanism-controlling pin L having its end formed with a fiat portion L, and means for holding said pin within the shuttle until the thread is nearly exhausted and then projecting the end out of the shuttle in position to engage mechanism of the loom.

In witness whereof We have hereunto signed our names, this 4th day of April, 1903, in the presence of two subscribing witnesses CAMILLE BRUN. GUSTAVE BRUN.
